Abstract
A pressure-sensitive adhesive articleincludes a release sheetconstituted from a releasing agent layerand a base material, and a pressure-sensitive adhesive sheetconstituted from a pressure-sensitive adhesive layerand a pressure-sensitive adhesive sheet base. Such a pressure-sensitive adhesive articlehas a structure in which the pressure-sensitive adhesive sheetis laminated on the release sheetso that the pressure-sensitive adhesive layeris in contact with the releasing agent layer. The releasing agent layeris composed of a material containing substantially no silicone compound. The releasing agent layeris mainly composed of an elastomer and has a Young's modulus of 1.5 GPa or less. Preferred examples of the elastomer include polybutadiene rubber (especially, 1,4-polybutadiene rubber), polyisoprene rubber, and ethylene propylene rubber. The release sheethas excellent releasability and has little adverse effect on electric components and the like.
